WATER-CLOSET VALVE MECHANISM. I.

SPECIFICATION forming part of Letters Patent No. 434,778, dated August 19, 1890.

Application filed February 13, 1890. Serial No. 340,276. (No model.) i

To all whom it may concern.-

Be it known th at 1, MILES HANKENHOF, of the city and county of New York, in the State of New York, have invented a certain new and useful Improvement in \Vater-Closet Valve Mechanisms, of which the following is a specification.

The invention applies to all that class 0 water-closets in which the flushing-water is admitted through a valve controlled by a float. Usually constructed, such valves are opened by the descending movement of the float when the water-level sinks, but have been closed by the action of a spring. It is difficult or impossible to provide springs which will act reliably. I extend the valvestem farther upward and so connect the lever with it that while the action of the float in descending opens the valve in the same manner as heretofore the action of the float in rising lifts the valve positively to its seat; and I provide a double chamber in which the float works, and also a large discharge-valve, with provision for operating the latter by hand without interfering with the action of the float. My valve for admitting the fresh supply after the bowl has been emptied is inclosed in the discharge-compartment. There is a deep but narrow passage between this and the part in which the float is accommodated; WVhen the reception of fresh water is retarded, the float continues to rise and presses the valve tightly to itsseat.

The accompanying drawings form a part this specification and represent what I consider the best means of carrying out the invention.

Figure 1 is a plan view with the cover of the double side chamber removed. Fig. 2 is a vertical section on the line :1; 0c in Fig. 1. Fig. 3 is a vertical section on the line y y in Fig. 1. Fig. 4 is on a larger scale. It is a vertical section through my valve in the position corresponding to that in Fig. 2.

Similar letters of reference indicate corresponding parts in all the figures where they appear.

A is the bowl, supposed to be of white crockery, and A A A a side chamber of cast-iron or other suitable strong material. The chamber is provided with a cover A The central part A is deeper than the other parts and connects directly with the bowl. The portion A accommodates the flushingvalve, which valve is operated bya lever extending across the central chamber A and connected to a float in the more distant portion A The portion A is connected with the portion A by a neck a, which is of sufficient depth to allow all the movement required for the lever, but is contracted in its width, so as to only leave little more than sufficient space for the lever to move freely. The contraction of this space makes the chamber A slow to fill and slow to empty, thus insuring a corresponding moderation in the movements by which the valve is opened and closed.

13 is the casing or body of the valve, and B the horizontal partition having the aperture in it for the passage of the water. It has a nicely-finished seat in the form of a rim 1). O is a coupling by which it is connected to the pipe through which the water is received.

D is is a puppet-valve opening downward, guided by wings on the stem D. It is provided with a soft face of vulcanized indiarubber or other suitable material, which fits tightly against the rim 1) of the seat, making a very tight closing when the valve is lifted. The stem D is provided with a mortise d, through which the lever E is passed. One end of this lever E is pivoted to the valvecasing at e. The other end is provided with an efficient float E, which may be a hollow ball of copper.

F is a large valve having a hollow interior and open at the top. It is lifted when required by a handle f, connected to a rod f. The large opening controlled by this valve permits a rapid discharge from the bowl A A A &c., through the trapped pipe A WVhen the valve F is opened by lifting on the knob f, all the contents of the bowl A and of the chamber A, &c., are rapidly discharged through the pipe A The water in the chamber A flows out slowly through the narrow neck a and the float E sinks. This, through the action of the lever E, depresses the stem D and opens the valve D. The water flowing past the valve D enters the bowl through the pipe G. As it accumulates in the bowl and connected chambers, the float E is tardily raised by its flowing through the narrow neck a, and the valve D is gradually closed. This movement of the valve is effected by the direct action of the lever E on the stem D. The narrow neck a affords so contracted a passage for the water that while the bowl is filling the water-level in the chamber A is somewhat lower than in the other parts. This condition obtains till the a valve closes by the lifting of the float E.

lowers the float sufficiently to open the valve and the filling of the bowl with water commences.

I claim as my invention- The chamber A", connected by a narrow vertical passage a with the chamber A, connected with the main bowl A, in combination with the lever E, arranged to play up and down in the slota, and with the float E rising and sinking in the camber A and with the induction-valve casing B, and with the valve D mounted therein, this valve being positively connected to the lever E, substantially as herein specified.

In testimony whereof I have hereunto set my hand, at New York city, New York, this 11th day of February, 1890, in the presence of two subscribing witnesses.
